AC-DC Battery Backed Power Supply
Block Diagram and Alarm Signals (G & L versions)
Derating Curves
Alarm Signals for AC OK and Battery Low
• These signals are open collector transistors and therefore an external voltage source and pull-up resistors are required
• The maximum applied external voltage is 50V and the maximum sink current is 30mA
Function Description Output of alarm
AC OK
Signal is ‘LOW’ when the power supply turns on. Low (0.3V max. at 30mA)
Signal is ‘HIGH’ when the power supply turns off High or open (externally applied voltage 30mA max.)
BAT. LOW
Signal is ‘LOW’ when battery voltage is under G:12V, L:22V Low (0.3V max. at 30mA)
Signal is ‘HIGH’ when battery voltage is above G:12V, L:22V High or open (externally applied voltage 30mA max.)
